NGC 3750 is the brightest member of a small group of galaxies, known as Copeland's septett. The group is also known as Hickson 57C and is located in eastern Leo. In a 12" telescope the two brightest galaxies can be observed under dark skies, however to see all 7 galaxies at least a 16" telescope is required.

Combination of 10, 3 minute exposures unfiltered.
